HSV stands for Hue, Saturation, Value. Hue is the color angle (0–360°), Saturation is the intensity (0–100%), and Value is the brightness (0–100%). It is also called HSB (Hue, Saturation, Brightness).

What is the difference between HSV and HSL?

Both use Hue and Saturation, but differ in the third channel. HSV uses Value (brightness of the color), while HSL uses Lightness (closeness to white or black). A fully saturated red is hsv(0, 100%, 100%) but hsl(0, 100%, 50%).

What RGB values should I enter?

Each channel — Red, Green, and Blue — takes an integer from 0 to 255. For example, pure red is R=255, G=0, B=0.

Is HSV the same as HSB?

Yes. HSB (Hue, Saturation, Brightness) is another name for the same color model. The math and channel ranges are identical.

Can I convert HSV back to RGB?

Yes. Use the HSV sliders in the Reverse panel at the bottom. As you move them the RGB values update in real time so you can copy them directly.

Does this tool send my data anywhere?

No. All conversion math runs entirely in your browser using JavaScript. No data is sent to any server.

Summary

This tool converts RGB (Red, Green, Blue) color values to the HSV (Hue, Saturation, Value) color model used in image editors and computer vision. Enter R, G, and B values from 0 to 255, and the tool outputs the corresponding hue angle (0–360°), saturation percentage, and value (brightness) percentage. A live color swatch updates instantly, and reverse HSV sliders let you work in the opposite direction.

How it works

Enter R, G, and B values (each between 0 and 255) in the input fields.
The HSV output — Hue (°), Saturation (%), and Value (%) — updates instantly.
A color swatch previews the exact color.
Click "Copy HSV" to copy the hsv() string to your clipboard.
Use the HSV sliders in the reverse panel to build a color and see the RGB values update live.

Use cases
